This mug is working out well for me. Really keeps coffee warm until the last gulp. Very sturdy. A couple reviewers had issues with broken handles and top hinged covers. And I noticed that when screwing on-off the lid that I was holding it by the handle and it was putting a lot of stress on the weld. Holding it by the bottom of the mug avoids problems. Also caught myself using the hinged cover as a lever to help screw down and/or off the lid. I'm sure that could eventually break it. Also wish it was still made in USA. I'd pay a few bucks more. Nice item in any case.

Bought this a week ago. It was love at first sight. Comfortable in the hand, well insulated for long heat retention, Effective lid seal.
I want to second the other comment about the vent hole location. It's right where my nose hits the lid, so after a small sip, it develops an airlock, and no more coffee flows, until, that is, I give up and tip the mug down slightly, when I get a big gulp when I least expect it. This would be very dangerous if it were to happen with scalding hot coffee, but so far I've been lucky and I've only encountered it when the cup is half-full and has cooled somewhat. Please redesign your lid to have two vent holes spaced about 3/4" apart, so this situation won't happen again.

Bought this around this time last year and it was my best purchase of the year.

Used virtually every day, keeps my coffee hot - warm for around 3 hours.

The only downside is the drinking spout isn't 90 degrees the the handle but I'm probably only griping because I'm a precision engineer.

Still in excellent condition despite 1 year old.

I'm hoping Stanley sell the rubber seals separately because I can't find any that diameter. Highly recommend this mug.

I bought this for my husband for Christmas in December I had to take it back because the handle fell off, the retailer exchanged it for me. My husband brought it home again this week, the same exact problem? Why is this happening? We have always purchased your products and never had any problems in the past.I thought I would recommend this product but something is not right with your procedure attaching the handle? I think you need to look into this. Have you received complaints about the handle from other customers?
